BACKGROUND

The present invention relates to cloud applications, and moreparticularly to hybrid cloud applications.

A hybrid cloud environment is a cloud computing environment that may usea mix of on-premise (e.g., private cloud) services and public cloudservices. The hybrid cloud may allow workload execution to move betweenprivate and public clouds as required by computing needs. Forapplications to successfully execute in the hybrid cloud environment,there must be an orchestration between the two platforms. By allowingworkloads to move between private and public clouds as computing needsand costs change, hybrid cloud gives businesses greater flexibility andmore data deployment options. Hybrid cloud is particularly valuable fordynamic or highly changeable workloads.

Services in a hybrid cloud environment may consist of a portion of anapplication specifically developed for and deployed in a public cloudenvironment. Additionally, there may be a portion of the applicationthat is developed for and deployed on a specific on-premise environment.Once deployed, the cloud and on-premise services may communicate andwork seamlessly together.

DETAILED DESCRIPTION

In today's highly computerized world, the daily operation ofcorporations, as well as the activities of individuals are highlydependent on computers. Corporations rely on computers and computerapplications to operate their business and to provide services to theircustomers. Many corporations use cloud computing practices to offeronline services to their customers. The cloud may be a network of remoteservers accessible via the internet (as opposed to a local, corporateowned resources) to store, manage, and process data

Use of the cloud offers many advantages, such as streamlined andimproved accessibility, as well as reduced capital and infrastructurecosts. Even though a corporation may offer services via the cloud, thecorporation may prefer to keep its confidential data on-premise due tosecurity and privacy concerns. This may be especially true forcompanies, such as banking and insurance companies, that treat thecustomer's data as highly confidential.

Companies that offer services (e.g., web services) via the cloud andmaintain data on-premise may encounter the need for the cloud servicesand on-premise services to communicate and work together. A cloudcomputing environment which uses a mix of cloud services and on-premiseservices is known as a hybrid cloud. The hybrid cloud architecture is anenvironment enabling applications deployed on the cloud to workseamlessly with applications deployed on an on-premise system. In ahybrid cloud environment, there is a need to have a secure,bi-directional connection between the cloud and the on-premise networkenabling protected communication.

In addition to networking concerns, developers of hybrid applications(i.e., applications running in a hybrid environment) must also beconscious of programming model and security concerns. In many instances,the cloud application and the on-premise application are developed bydifferent developers, resulting in programming, security, andinstallation differences. The embodiments disclosed herein generallyaddress the above-described problems.

The present invention will now be described in detail with reference tothe Figures. FIG. 1 is a functional block diagram depicting a hybridcloud environment 100, in accordance with an embodiment of the presentinvention. Hybrid cloud environment 100 includes cloud platform 110,on-premise platform 160, and client 180. Cloud platform 110, on-premiseplatform 160, and client 180 can include smart phones, tablets, desktopcomputers, laptop computers, specialized computer servers, or any othercomputer systems, known in the art, capable of communicating overnetwork 190. In general, cloud platform 110, on-premise platform 160,and client 180 are representative of any electronic devices, orcombination of electronic devices, capable of executing machine-readableprogram instructions, as described in greater detail with regard to FIG.4.

Cloud platform 110 may be a public cloud environment capable of hostingweb applications and providing services for users, such as client 180.As depicted, cloud platform 110 includes a connectivity service 112,persistent storage 118, a hybrid cloud application package 120, and acloud application container 130. On-premise platform 160 may be aprivate environment (e.g., a private cloud) of a corporation providingweb applications on cloud platform 110. On-premise platform 160 includesa cloud gateway 162, persistent storage 168, and an on-premiseapplication container 170.

Hybrid cloud application package 120 contains two distinct deployableapplication packages (cloud manifest 122 and on-premise manifest 124)that are to be deployed on cloud platform 110 and on-premise platform160. Cloud manifest 122 contains information to properly launch cloudapplication container 130, as well as an application, deploymentinstructions, and startup parameters for a cloud application that willbe deployed on cloud platform 110. On-premise manifest 124 containsinformation to properly launch on-premise application container 170, aswell as deployment instructions, startup parameters, and librarydependencies of an on-premise application that will be deployed onon-premise platform 160.

Hybrid cloud application package 120 may be loaded to cloud platform 110over network 190. When the cloud application package 120 is loaded tocloud platform 110, connectivity service 112 may establish a securebi-directional communication tunnel 150 between cloud platform 110 andon-premise platform 160. Secure tunnel 150 may bridge the communicationbetween cloud platform 110 and on-premise platform 160, enabling anapplication running in cloud application container 130 to easilycommunicate with an application running in on-premise applicationcontainer 170 without knowing the IP address of cloud gateway 162.

After the cloud application is successfully deployed and running incloud application container 130, on-premise manifest 124 is transferredto on-premise platform 160 via secure tunnel 150. After beingtransferred to on-premise platform 160, on-premise manifest 124 launcheson-premise application container 170, deploys the on-premiseapplication, and starts the application. Part of the deploy operation,each container (e.g., cloud application container 130 and on-premiseapplication container 170) contain a messaging component (e.g., forexample message client library 132 in cloud application container 130and message broker 172 in on-premise application container 170). Thecloud application executing in cloud application container 130 and theon-premise application executing in on-premise application container 170can communicate with each other using a pub/sub programming model.

Client 180 may be any client that communicates with cloud platform 110and cloud application container 130 over network 190. On-premiseplatform 160 may be a web server, an application server, or anycomputing device capable of receiving traffic over secure tunnel 150.Cloud application container 130 may provide a public online webapplication (e.g., a banking application, an auction site, a videostreaming site, or the like), a corporate internal services (e.g., abilling application, human resources data retention, internal email, andthe like), or any other services capable of being run on a computingdevice. Cloud platform 110 and on-premise platform 160 may be ofdiffering hardware architectures. For example, cloud platform 110 may behosted on mainframe computers, while on-premise platform 160 may behosted on a personal computer.

Persistent storage 118 and 168 may be any non-volatile storage mediaknown in the art. For example, persistent storage 118 and 168 can beimplemented with a tape library, optical library, one or moreindependent hard disk drives, or multiple hard disk drives in aredundant array of independent disks (RAID). Similarly, data onpersistent storage 118 and 168 may conform to any suitable storagearchitecture known in the art, such as a file, a relational database, anobject-oriented database, and/or one or more tables.

Cloud platform 110, client 180, and other electronic devices (not shown)communicate over network 190. Network 190 can be, for example, a localarea network (LAN), a wide area network (WAN) such as the Internet, or acombination of the two, and include wired, wireless, or fiber opticconnections. In general, network 190 can be any combination ofconnections and protocols that will support communications between Cloudplatform 110 and client 180, in accordance with an embodiment of thepresent invention.

FIG. 2 is a flowchart depicting a cloud platform method 200, inaccordance with at least one embodiment of the present invention. Asdepicted, cloud platform method 200 includes receiving (210) a hybridcloud application package, deploying (220) a deployable cloud package ina container, establishing (230) a secure bidirectional communicationtunnel, sending (240) a deployable on-premise package to an on-premiseserver, sending (250) a message requesting services form an on premiseapplication, and receiving (260) a response from the on-premiseapplication. Cloud platform method 200 enables cloud platform 110 todeploy the cloud portion of a hybrid cloud application, initiate thedeployment of an on-premise portion of the hybrid cloud application, andestablish a secure communication tunnel between the cloud and on-premisehybrid cloud applications.

Receiving (210) a hybrid cloud application package may include cloudplatform 110 receiving a single unit (e.g., hybrid cloud applicationpackage 120) that includes two applications (a cloud application and anon-premise application) to be deployed. The package may have beencreated using a programming model for hybrid cloud applications thatallows a developer to build both a cloud and an on-premise application(using container technology) as a single unit. Each of the twoapplications contained in hybrid cloud application package 120 may bedefined by a manifest (e.g., cloud manifest 122 and on-premise manifest124). Each manifest may correspond to a unique deployable package, forexample, cloud manifest 122 may correspond to a deployable cloudpackage, and on-premise manifest 124 may correspond to a deployableon-premise package

Deploying (220) a deployable cloud package in a container may includecloud platform 110 retrieving cloud manifest 122 from cloud applicationpackage 120. In some embodiments, cloud manifest 122 (the deployablecloud package) contains information (e.g., instructions) to properlylaunch cloud application container 130, as well as a cloud application,deployment instructions, startup parameters and library dependencies ofthe cloud application. Cloud platform 110 may use the deploymentinstructions to deploy the deployable cloud package in cloud applicationcontainer 110. In some embodiments the cloud application is included inhybrid cloud application package 120. In other embodiments, the cloudapplication is stored in another location (e.g., on persistent storage118) and is referenced by cloud manifest 122.

Establishing (230) a secure bidirectional communication tunnel mayinclude cloud platform 110 receiving retrieved connectivity informationfrom connectivity service 112. The connectivity information may include,among other things, an IP address and a connection port of cloud gateway162 corresponding to the on-premise environment (e.g., on-premiseplatform 160). In some embodiments, connectivity service 112 providesinformation corresponding to an existing secure bi-directionalcommunication tunnel (e.g., secure tunnel 150) to cloud platform 110. Inother embodiments, connectivity service 112 sets up a new securebi-directional communication tunnel (e.g., secure tunnel 150) andprovides connectivity corresponding to the new secure tunnel to cloudplatform 110.

Sending (240) a deployable on-premise package to an on-premise servermay include cloud platform 110 retrieving the deployable on-premisepackage (e.g., on-premise manifest 124) from hybrid cloud applicationpackage 120. The deployable on-premise package may be sent to on-premiseplatform 160 over a secure bi-directional communication tunnel (e.g.,secure tunnel 150). In some embodiments, the deployable on-premisepackage is sent to on-premise platform 160 as soon as the deployablecloud package has been successfully deployed. In other embodiments, thedeployable on-premise package is sent to on-premise platform 160 thefirst time a service corresponding to the deployable on-premise packageis requested.

After the on-premise application has been successfully deployed, cloudplatform 110 may initialize a messaging framework over secure tunnel 150to enable simplified communication between the containers in which thetwo deployed applications run (e.g., cloud application container 130 andon-premise application container 170). In some embodiments, messageclient library 132 is created to enable the cloud application to send amessage to the on-premise application.

Sending (250) a message requesting services form an on premiseapplication may include cloud application container 130 of cloudplatform 110 using a messaging framework to send a request to on-premiseapplication container 170 requesting specific services provided by anon-premise application running in on-premise application container 170.The message framework may utilize secure tunnel 150 to move messagesbetween cloud application container 130 and on-premise applicationcontainer 170. In some embodiments, the messaging framework usesmessaging modules (e.g., message client library 132 and message broker172) to encapsulate messages between different architectures. In oneexample, cloud application container 130 may be running a bankingapplication, and the user of the application wishes to electronicallytransfer money from one account to another. However, cloud applicationcontainer 130 does not have access to the actual user accounts, andtherefore message client library 132 sends a message to on-premiseapplication container 170 over secure tunnel 150 to request the transferbe processed. Message broker 172 receives the messages and theapplication running in on-premise container performs the service.

Receiving (260) a response from the on-premise application may includecloud application container 130 of cloud platform 110 receiving amessage from on-premise application container 172 indicating that aservice has been performed. In some instances, the response may be aconfirmation that the requested service has been performed. In otherinstances, the response includes information such as requestedinformation (e.g., an existing account balance), or the results of arequested action (e.g., a new account balance after an electronicpayment).

FIG. 3 is a flowchart depicting an on-premise platform method 300, inaccordance with at least one embodiment of the present invention. Asdepicted, on-premise platform method 300 includes receiving (310) adeployable on-premise package, deploying (320) a deployable on-premisepackage in a container, establishing (330) a messaging framework,running (340) an on-premise application on a restricted containerenvironment, receiving (350) a request for services, and sending (360) aresponse corresponding to requested services. On-premise platform method300 enables on-premise platform 160 to initiate the deployment of anon-premise portion of the hybrid cloud application in a restrictedcontainer, and securely provide services to a cloud portion of thehybrid cloud application.

Receiving (310) a deployable on-premise package may include on-premiseplatform 160 receiving from a cloud platform (e.g., cloud platform 110)an on-premise portion of a hybrid cloud application package (e.g.,receiving on-premise manifest 124 from hybrid cloud application package120). The deployable on-premise package may be received over securetunnel 150. In some embodiments, the deployable on-premise package isstored on persistent storage 168. In other embodiments, the deployableon-premise package is retained in memory for immediate deployment. Thedeployable on-premise package may include an on-premise application anddeployment instructions for the on-premise application.

Deploying (320) a deployable on-premise package in a container mayinclude on-premise platform 160 parsing on-premise manifest 124 toidentify what deployment operations are required. In some embodiments,on-premise manifest 124 contains instructions to launch on-premiseapplication container 170. In some embodiments, on-premise manifest 124contains instructions to deploy and start the on-premise application.On-premise platform 160 may use the deployment instructions to deploythe deployable on-premise package in on-premise application container170. The on-premise application container 170 and on-premise applicationmay be deployed in a perimeter network, also known as a demilitarizedzone (DMZ) which may add an additional layer of security between apublic cloud (e.g., cloud platform 110) and an organization's local areanetwork (LAN). Cloud platform 110 only has direct access (via tunnel 150through cloud gateway 162) to resources in the DMZ, rather than anyother part of the organization's network. However, the on-premiseapplication can access the on-premise network and therefore is able toprovide services that require access to on-premise resources.

Establishing (330) a messaging framework may include on-premise platform160 using secure tunnel 150 and messaging framework technology toprovide simplified hybrid cloud communication. In some embodiment, uponsuccessful deployment of the on-premise application, a message broker isautomatically deployed to on-premise application container 170 tofacilitate a secure messaging framework. In some embodiments,establishing operation 330 coincides with similar messaging frameworkactivities on cloud platform 110. The message framework may include amessage client library 132 corresponding to cloud application container130 and message broker 172 corresponding to on-premise applicationcontainer 170.

Running (340) an on-premise application on a restricted containerenvironment may include on-premise platform 160 retrieving, fromon-premise manifest 124, startup information. Startup information mayinclude required prerequisite dependencies, application startuplocation, application startup commands, and application startup commandparameters. When the on-premise application is fully initialized (e.g.,running and ready to accept requests), the application may be preparedto provide one or more services. In some embodiments, after a period ofinactivity, the application enters a sleep state and re-activates when amessage requesting services is received on a message framework. In otherembodiments, the application remains fully active until the applicationis shut down.

Receiving (350) a request for services may include on-premise platform160 using a messaging framework to receive, over secure tunnel 150, amessage requesting services that may be provided by the on-premiseapplication. Message broker 172 may translate the messaging from themessaging protocol of the sender to the messaging protocol of on-premiseplatform 160. In some embodiments, message broker 172 performsadditional authentication to confirm the request originated from anauthorized requester. The on-premise application, running in on-premisecontainer 170 may receive the message, determine what services are beingrequested, and perform the requested services.

Sending (360) a response corresponding to requested services may includeon-premise platform 160 completing a requested service request. Uponcompletion of the service request, on-premise application container 170may respond to a requester (e.g., cloud application container 130)indicating that the request has completed. In some embodiments, theresponse includes results of the requested service. In otherembodiments, the response contains an indication of success or failureand a reference (e.g., a pointer, or a url) providing a location toobtain any additional results of the service. In some embodiments, theresponse contains an indication of success or failure of the requestwithout providing any additional details or data.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g., networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elasticallyprovisioned, in some cases automatically, to quickly scale out andrapidly released to quickly scale in. To the consumer, the capabilitiesavailable for provisioning often appear to be unlimited and can bepurchased in any quantity at any time.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based e-mail).The consumer does not manage or control the underlying cloudinfrastructure including network, servers, operating systems, storage,or even individual application capabilities, with the possible exceptionof limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting forload-balancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure comprising anetwork of interconnected nodes.
